Question

我有两个实体：

课程和期间

两者都可以通过联接表链接。在TCA课程中，期间定义为内联，因此我可以为每个课程添加新的期间。这些条目正确存储在联接表中。在课程TCA上，正确显示了链接的“期间”。当我通过PeriodRepository获得一个期间并尝试按每个期间获取课程时，结果为空。如何按期访问课程？

TCA课程：

 'periods'              => [
        'exclude' => true,
        'label'   => 'LLL:EXT:courses/Resources/Private/Language/locallang_db.xlf:tx_courses_domain_model_period',
        'config'  => [
            'type'                             => 'inline',
            'foreign_table'                    => 'tx_courses_domain_model_period',
            'MM'                               => 'tx_courses_course_period_mm',
            'enableMultiSelectFilterTextfield' => true,
            'MM_opposite_field'                => 'courses',
            'appearance'                       => [
                'useSortable'  => 1,
                'collapseAll'  => 1,
                'expandSingle' => 1,
            ]
        ],

    ],

TCA期限：

        'courses'          => [
        'exclude' => true,
        'label'   => 'LLL:EXT:courses/Resources/Private/Language/locallang_db.xlf:tx_courses_domain_model_module.courses',
        'config'  => [
            'type'              => 'select',
            'multiple'          => 1,
            'foreign_table'     => 'tx_courses_domain_model_course',
            'MM'                => 'tx_courses_course_period_mm',
            'MM_opposite_field' => 'periods',
        ],

    ],
